background subtraction with a moving camera

edit

I took part in a project where we detected cars from a flying camera. The assumption was that the camera was high enough to treat the ground as flat. In such a case, we were able to find homography between consecutive frames and stitch them together. Since two neighboring frames usually overlap substantially, we could detect differences in them AFTER stitching/overlaying. Actually we used more than just 2 frames, but if I remember well, less than 10 due to camera movement. Unfortunately, since the number of overlaying frames was not big, it was not possible to use some advanced background removal methods (like GMM for example) as they need several frames to learn the background. However, if your camera is not going to move too much, that could be possible.

Nobody can help? I mean, if somebody who already has had to do such thing was kind enough to explain to me his method, that would really help!

Hello there,
I'm having the same problem: subtracting two frames works just fine with a static background but I'm dealing with a moving camera as well. Anyone has any ideas on how to do get rid of a moving background?

Actually, my situation is the following: I need to detect moving submarine wildlife, but I get a lot of useless info (other moving things that aren't useful at all ->seaweed etc...) and the camera moves, so the background changes.
Any help will be much appreciated, (I'm not specifically asking for code, what I would like to have are ideas, because I'm running out of those)
thanks in advance for your replies.

I managed to solve my problem, thanks for your reply anyway :)
